Design and Realization of Water Distribution Experiment System for High-power Pressurized Water Reactor PCS
摘要
Abstract
Aimed at the water flow characteristic under design basis accident (DBA) for high-power pressurized water reactor passive containment cooling system ,a full scale but sector style of the containment was adopted . In order to study the relationship between the flow rate and the key parameters such as water film coverage rate ,quasi-steady time etc .,an ellipsoid sector test facility and respective measurement system were designed .A high-speed image measurement system for large curvature surfaces was also designed .The water film thickness measurement system was designed to obtain the accurate film thickness data by non-contact electric capacitance probes and related three-dimensional adjustable bracket system .All the important measurement systems were calibrated .Preliminary analysis results show that the design of test body and loop is reasonable .The trends of water film coverage rate and the relative quasi-steady time with different Reynolds numbers are obtained .关键词
